There is a problem about toad.quality

[ivring2]

My code：

import toad
iv_info = toad.quality(df_train,'isDefault', iv_only=True)

I would be grateful if you could help me solve this problem

@ivring2 do you use select function before quality?

[yangjlx]

我也遇到了一样的报错，0.1.1版本的，使用 fit 函数的时候。
具体报错是在
toad/utils/func.py
def np_count(arr, value, default = None):
c = (arr == value).sum()
...

AttributeError: 'bool' object has no attribute 'sum'
